== Autophagy vis-a-visupavasa ==
 +
<ul style="text-align:justify;"><li>Autophagy (self-eating) is a metabolic process in which the cell eliminates non-essential components via a lysosome-dependent, regulatory mechanism. It transforms cellulardetritus into survival-essential energy.</li>
 +
<li>Autophagy occurs in our body primarily during the energy deprivation phase, such as fasting. Fasting destroys metabolic toxins, ignites the digestive fire and clears all the blockage in our body's channels, which ultimately provides good health. Fasting is a ubiquitous religious and cultural practice that is found, in varying forms, across the world.</li>

<li>Fasting stimulate autophagy,it helps in the cell renewal process and it also help in declining the aging process.</li></ul>

<li style="font-weight:bold">Fasting and self-control:<br/><span style="font-weight:normal">The findings of a famous psychology experiment termed the [https://en.wikipedia.org/wiki/Stanford_marshmallow_experiment Stanford marshmallow experiment], are closely related to the traditional reason behind fasting. In the experiment, children were left in a room alone for 15 minutes and given a candy. They were given a promise that if the child did not eat the candy at the end of the 15 minutes, he/she would get two candies. Children who could control the temptation for 15 minutes to get the reward were later tracked in life. After 2 decades, they became way more successful than the kids who got tempted to eat the candy as soon as they were given it. Fifty years post the experiment, the researcher talks about self-controlas a muscle that must be exercised and built.</span></li>

J Cell Biol. 2012;197(2):164-165. doi:10.1083/jcb.1972pi</ref><br/><span style="font-weight:normal">The controlled digestion of internal cell components is called autophagy.Basically, when we give fuel to mitochondria, when they don’t need them, they release a large number of electrons, giving rise to reactive oxygen species that act as free radicals. These free radicals damage not only mitochondria, but also nuclear DNA. Yoshinori Ohsumi a cellular biologist from Japan, was awarded a Nobel Prize in 2016 in physiology and medicine for discovering the importance of autophagy for many physiological processes such as adaption to fasting and the Mechanism of Autophagy.</span></li></ol>
